Ontologies and Ontological Representation
Ovidius University Annals: Economic Sciences Series, 2020 The present paper aims to present the main theoretical and practical aspects of what ontology and knowledge bases mean, having the role of providing as precise information as possible. Ontologies are considered to be a vocabulary of concepts, and the purpose of this "vocabulary" is to ensure a semantically based level of knowledge based on semantics in

FEBS Open Bio, EarlyView.Clinical analysis reveals significant dysregulation of FGFRL1 in esophageal cancer (EC) patients. RNAi‐coupled next‐generation sequencing (NGS) and in vitro study reveal FGFRL1‐mediated EC progression via EMT, PI3K/Akt, and Notch pathways. Functional assays confirm its role in tumor growth, migration, and invasion.

A visual representation of part-whole relationships in BFO-conformant ontologies [PDF]
, 2017 In the visual representation of ontologies, in particular of part-whole relationships, it is customary to use graph theory as the representational background.

The Plant Ontology™ Consortium and Plant Ontologies [PDF]
Comparative and Functional Genomics, 2002 AbstractThe goal of the Plant Ontology™ Consortium is to produce structured controlled vocabularies, arranged in ontologies, that can be applied to plant‐based database information even as knowledge of the biology of the relevant plant taxa (e.g. development, anatomy, morphology, genomics, proteomics) is accumulating and changing.

FEBS Open Bio, EarlyView.dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

, 2001 Ontologies are studied by many scholars with diverse backgrounds and are applied in a variety of contexts and application areas. Despite the numerous reviews published there are many issues which still remain unclear with respect to their cost-effective deployment, identification of tradeoffs, maintenance strategies and ways of integration. Furthermore,

Spatial groundings for meaningful symbols [PDF]
, 2009 The increasing availability of ontologies raises the need to establish relationships and make inferences across heterogeneous knowledge models. The approach proposed and supported by knowledge representation standards consists in establishing formal ...

Conceptual Modelling and The Quality of Ontologies: Endurantism Vs. Perdurantism
, 2012 Ontologies are key enablers for sharing precise and machine-understandable semantics among different applications and parties. Yet, for ontologies to meet these expectations, their quality must be of a good standard.
